I was on a Carnival ship two years ago and it was awful. The food was terrible (the Americans and their french fries) and the smoke on board was as thick as pea soup.

Welcome to Cruise-Chat!

Food quality on board any line is a subjective type personal assessment. You'll find the majority of Carnival cruisers think the food is wonderful. As far as the smoke being as thick as pea soup, I disagree with that comment as it is an exaggeration. Carnival has limited smoking areas. The same is currently true of Holland America Line.
